s intended to be less likely to kill a living target than are conventional weapons. It is often understood that accidental, incidental, and correlative casualties are risked wherever force is applied, but non-lethal weapons try to minimise the risk as much as possible. Non-lethal weapons are used in combat situations to limit the escalation of conflict or where employment of lethal force is prohibited or undesirable or where rules of engagement require minimum casualties or policy restricts the use of conventional force.

and Heidi Toffler reported comprehensively on this phase of the history of non-lethal weapons in their 1993 book, War and Anti-War. The U.S. Congress and other governments agreed and began an organized development of non-lethal weapons to provide a range of options between talking and shooting.

Recognizing the need to limit the escalation of force, research and development of a range of non-lethal weapons has since been undertaken internationally by governments and weapons manufacturers to fill the need for such weapons. Some non-lethal weapons may provide more effective riot control than firearms, truncheons or bayonets with less risk of loss of life or serious injury. Before the general availability of early military non-lethal weapons in the mid 1990s, war-fighters had few or no casualty-limiting options for the employment of scalable force and were continually at risk whenever lethal force was prohibited during sensitive missions.

but no lasting damage. The skin temperature of a person subjected to this weapon can jump to approximately 130 °F (54.4 °C) in as little as 2 seconds depending on the skin's starting temperature. The system is nonlethal (the penetration of the beam into human skin is only a few millimeters).

In 2004, author Jon Ronson cited an unclassified military report titled "Non-Lethal Weapons: Terms and References" 21 acoustic weapons were listed, in various stages of development, including the Infrasound ("Very low-frequency sound which can travel long distances and easily penetrate most buildings and vehicles ... biophysical effects are projected to be: nausea, loss of bowels, disorientation, vomiting, potential internal organ damage or death may occur. Superior to ultrasound...)", however no such effects had been achieved .

Recent history of non-lethal options for employment by police

Until the development of non-lethal weapons, police officers around the world had few if any non-lethal options for riot control. Common tactics used by police that were intended to be non-lethal or less lethal included a slowly-advancing wall of men with batons, officers on horses trained to deal with policing situations, or a charge into a riot using the flats of sabers. Other reasonably successful approaches included shotguns with lower-powered cartridges, "salt shells", and ricocheting the shot off of the ground. In the mid 1900s, with the integration of fire-control systems into major cities, police found that high-pressure fire hoses could be effective in dispersing a crowd (the use of water cannon

by private citizens. However, these weapons were developed for non-lethal resolution of a one-on-one conflict.

During the 1990s and early 2000s interest in various other forms of less-than-lethal weapons for military and police use rose. Amongst other factors, the use of less-than-lethal weapons may be legal under international law and treaty in situations where weapons such as aerosol sprays or gases defined as chemical are not. Less-than-lethal weapons are also useful in keeping the peace in the aftermath of violent conflict.

, the active ingredient in pepper spray, and is propelled by compressed gas using a paintball marker similar to those used for the sport but operating at higher pressure. The impact of the capsule is immediately painful (a pepperball's shell is thicker than a standard paintball and is fired at higher velocity), and it breaks open on impact, dispersing the capsaicin with similar effect to aerosol-delivered pepper spray. However, to be most effective, pepper spray must contact the eyes, nose, or mouth of the target; pepper spray on clothing or tougher skin has a much reduced effect.

Effects

Non-lethal weapons ability to incapacitate with minimal lasting effects has made them the weapon of choice for use in civilian populations. However, some analysts describe "non-lethal" as a misnomer and instead define them as "less-lethal".

Contemporary caltrops look something like large jacks from the childhood game.

warfare for a long time. However, due to the difficulty of mass-producing them in the pre-modern age, they were rarely used except in the defense of limited areas or chokepoints, especially during sieges, where they were used to help seal breaches.

will incorporate non-lethal weapons.

Mechanics

Non-lethal weapons are intended to minimize injury or death. While people are occasionally seriously injured or killed by these weapons, fatalities are relatively infrequent. Causes of death from non-lethal weapons are varied and occasionally uncertain. Misplaced or ricocheting shots, pre-existing medical conditions, inadequate user training, repetitive applications and intentional misuse have been implicated in different cases where death has occurred.

As different parts of the body differ in vulnerability, and because people vary in weight and fitness, any weapon powerful enough to incapacitate may be capable of killing under certain circumstances. Thus "non-lethal force" does have some risk of causing death: in this context "non-lethal" means only "not intended to kill".

Several groups maintain there is great room for improvement in non-lethal weapons and procedures for their use. Claims for the relative safety of such weapons are usually contingent on their being used "properly." For example, the rubber bullet

an unsuccessful attempt to use an unknown gas - thought to be fentanyl, or 3-methylfentanyl

3-Methylfentanyl

3-Methylfentanyl is an opioid analgesic that is an analogue of fentanyl. 3-Methylfentanyl is one of the most potent drugs that has been widely sold on the black market, estimated to be between 400-6000 times stronger than morphine depending on which isomer is used .3-Methylfentanyl was first...

, for inducing sleep in the terrorists and hostages, caused the deaths of many hostages, some from choking on their vomit, others from an overdose, while many of the Chechen terrorists survived using gas masks and were able to fight the Russian forces (still, the suicide bombers among the hostages lost consciousness, as projected). The Russian government was accused of using the gas, knowing that many of the hostages would die as a result, but this has never been proved. Sleeping gas has not been used by armed forces since.

policy explicitly states that non-lethal weapons "shall not be required to have a zero probability of producing fatalities or permanent injuries." Although a Human Effects Advisory Panel was established in 1998 to provide independent assessment on human effects, data, and models for the use of 'non-lethal weapons' on the general population, the TECOM Technology Symposium in 1997 concluded on non-lethal weapons: "Determining the target effects on personnel is the greatest challenge to the testing community," primarily because "the potential of injury and death severely limits human tests." However, "directed energy weapons
